Explain the negative feedback loop that regulates spermatogenesis at homeostatic levels. Testosterone acts in a negative feedback manner on anterior pituitary gonadotrophs to suppress the secretion of LH. The negative

Stress‚ the disruption of the homeostatic balance by internal or external influences‚ is inherent‚ inevitable and exists in every stages of life‚ starting as early as the fetal stage till one’s death. In particular‚ early life stress (ELS) has come to light in recent years as it is becoming more prevalent and epidemiological studies have shown that ELS increases one’s vulnerability to subsequent stressors‚ leading to a multitude of stress-related neuropsychiatric disorders such as depression and

The vagus nerve is the tenth of the twelve brain nerves. The vagus nerve contributes to the feelings associated with infections such as appetite‚ fatigue and induction of disease behavior. It extends from the brainstem to the abdomen‚ with branches in the neck‚ thorax and abdomen 68. The vagus nerve is part of the autonomic nervous system‚ has efferent fibers‚ ascending signals from the brain to the peripheral organs‚ as well as afferent sensory fibers‚ and transmits information from the peripheral

The Structure & function of the Autonomic Nervous System Introduction: The organs of our body are controlled by many systems in order to function correctly and efficiently in order to survive within the environment we live in. These include the heart‚ stomach and intestines and other vital organs and body systems. All of the systems in our body are regulated by a part of the nervous system called the autonomic nervous system (ANS). The ANS is part of the peripheral nervous system and it controls
